Want to hide part of your message so others can choose whether or not to see it? That’s what spoiler tags are for!
You can use spoilers to:
- Hide hints or answers in a challenge
- Blur text that might give something away
- Let others try first before revealing more
How to add a spoiler
Click the little gear icon 
in the formatting bar and choose Blur Spoiler.
Or type it directly like this:
[spoiler]This is hidden text[/spoiler]
It will look like this:
This is hidden text
You can also hide images
To blur an image, you can select it and blur it just like text!
Or if you can switch the composer into Markdown mode and add spoiler tags around it like this:
[spoiler]
[/spoiler]
It will show up blurred until clicked.
